'Walking Dead' spin-off in the works at AMC

There will be no Rick Grimes in "The Walking Dead" spin-off, but expect zombies.

AMC is bringing more zombies to TV! The network announced Monday that it is working with Robert Kirkman, creator of "The Walking Dead" graphic novels, and the show's executive producers Gale Anne Hurd and David Alpert to do a companion series.

Charlie Collier, AMC's president, called the decision "a no-brainer" in a statement, and revealed that the show will consist of an entirely new cast of characters and will be a new story. "It's a big world and we can't wait to give fans another unforgettable view of the zombie apocalypse," he said.

The new show is expected to premiere in 2015.

"After 10 years of writing the comic book series and being so close to the debut of our fourth, and in my opinion, best season of the TV series, I couldn't be more thrilled about getting the chance to create a new corner of 'The Walking Dead' universe," Kirkman said in a statement. "The opportunity to make a show that isn't tethered by the events of the comic book, and is truly a blank page, has set my creativity racing."

"The Walking Dead," starring Andrew Lincoln and Norman Reedus, premiered in 2010 and has since become the No. 1 TV show among viewers in the 18-49 demographic.

But long before the spin-off debuts, "The Walking Dead" will return for its fourth season. At Comic-Con this summer, the stars and producers teased that the show would "get insane very quickly" this year. Kirkman has also revealed that there will be a zombie baby of sorts, noting that the little one would be "different from the baby who was seen in 'Dawn of the Dead' remake."
